microscope lighting circuts

[science teach]

I have three EDUSCIENCE Big Screen microscopes for my science
classroom. I want to refit the non-working circuts to make them plug
into regular wall
outlet. Where can I find the parts and the help to make this happen.

The unit I had as a kid used 2 AA cells in the base (3 volts).
The mirror's gimbal was the return path (the frame was "ground")
and the mirror rotated 180 so that the bulb on the other side pointed up
and in so doing, the protruding hot terminal on the mirror/bulb holder
contacted a pad that was a voltage source.

Details like this would be helpful.
